Planning the Right Extension for Your Property - ADM Studio’s Top Tips

A well-designed home extension can completely transform how you live. Whether you’re dreaming of a spacious kitchen-diner, a light-filled garden room or an extra bedroom, a house extension is often the key to unlocking your property’s full potential.

At ADM Studio, we have helped homeowners reimagine their spaces with creative and considered architectural solutions. But before the builders arrive, good planning is everything. Here are our expert tips on choosing and designing the right extension for your home, with inspiration from some of our favourite projects.

1. Start with the Why

Before you get into materials and floorplans, ask yourself what you need from your extension. Are you looking for more family space? A better connection to the garden? A dedicated work-from-home area?

At Perth House, the homeowners wanted a bright, contemporary kitchen and dining area with views of the garden. We delivered a clean and modern single storey rear extension that feels like a natural continuation of the house while elevating its functionality.

Tip: Define the problem the extension is solving. That will guide every design decision that follows.

2. Understand Your Options

There are many types of home extensions, and the best one depends on your property type, budget and planning constraints.

Common options include:

• Rear extensions for open-plan living or kitchen upgrades
  
• Side return extensions to make better use of dead space
  
• Wraparound extensions to combine both and maximise internal flow
  
• Two-storey extensions to add multiple rooms across both floors
  
  

At Longstaff Crescent, we created a beautifully integrated side and rear extension, opening up the ground floor into a light and airy kitchen-living space. The additional volume transformed the property’s layout without compromising outdoor space.

Tip: Explore which type of extension will give you the most benefit within the footprint and planning rules of your plot.

3. Work With the Character of Your Home

Extensions should complement your existing home, whether through contrast or continuity.

Take Oakwood Cottage, a heritage property where we crafted a sensitive extension that matched the cottage’s traditional character. With carefully chosen materials and proportions, the new space blends seamlessly while offering modern comforts.

In contrast, at Clarence Road, we embraced bold contemporary design, with sharp lines, large glazing and a confident architectural form that redefined the rear of the home.

Tip: Think about how your extension will sit alongside the original architecture. It can either complement it subtly or create striking contrast.

4. Plan for Light and Flow

One of the biggest benefits of extending is the opportunity to rethink how natural light enters and moves through your home.

At Beechwood, we opened up the rear of the property to create a bright, flowing family space with expansive doors to the garden. Clever rooflights and window positioning made the space feel warm and welcoming all year round.

Tip: Use architectural elements like glazing, ceiling height changes and open-plan layouts to improve how your home feels, not just how it looks.

5. Consider the Long-Term Value

An extension is a big investment, so make sure it works for you both now and in the future. Think about resale value, energy performance and whether the space can adapt as your needs change.

We always encourage clients to think about flexibility. Could your new space become a playroom now and a home office later? Would a downstairs shower room add long-term convenience?

Tip: A well-planned extension should enhance daily life and add real value, both financially and emotionally.
